for those of you who have trouble with some games freezing on the loading screen i tried the executer2_4978.03_xboxmulti_512k bios and then installed slayers autoinstall 2.5 and now i can play backups on any media without patching the .xbe files.
hope this helps some people out there.

xbit 2mb bios mod chip installed with pogopins (no spacer)
samsung drive with latest firmware.
